An air layer holding block 15 which forms an air layer extending vertically and horizontally therein, and which constitutes the air layer holding block 14, is a projection sheet formed by processing a plastic sheet and projecting a large number of projections vertically and horizontally at a predetermined pitch. , 1
Reference numeral 6 denotes a projection formed on the projection sheet 15, reference numeral 17 denotes an air-permeable soft ventilation sheet laid on the upper surface of the projection 16 of the projection sheet 15, and reference numeral 18 denotes a waterproof, soft air-permeable sheet laid on the lower surface of the projection sheet 15. The waterproof sheet 20 is a sealing material.

In the first embodiment shown in FIGS. 1 to 6, a plurality of hangers 6 are arranged at predetermined intervals in the direction of the eaves on a roof surface formed by laying a roofing material 12 on an upper surface of a field board 11. The rows of sub-elements 6 are arranged side by side at intervals of about the width of a plurality of rows of roofing materials 1, the roofing materials 1 are respectively arranged between the rows of the hanging elements 6, and the recessed portions 2 of the roofing materials 1 are suspended. The hook 6 is fitted into the space between the pair of parallel portions 7 of the child 6, the claws 8 of the suspension 6 are engaged with the bent portion of the side wall of the recess 2 of the roof material 1, and the roof material 1 is attached to the roof surface. Fix it. Since the suspension 6 is made of spring steel, when the recessed portion 2 of the roofing material 1 is fitted, the pair of parallel portions 7 of the suspension 6 expands outward, so that the roofing material 1 can be removed without any tool. It can be locked to the suspension 6. Goby 5 for roofing material 1
Is inserted into the concave portion 2 of another adjacent roofing material 1, inserted into the goby insertion space 4 located above the concave portion 3 in the concave portion 2, and is locked. The gap between the side walls is filled with the sealing material 20 to seal. An air layer holding block 14 is interposed in the gap between the roofing material 1 and the roof surface to produce a heat retaining effect and a heat insulating effect. A cap 9 is fitted into the recess 2 of the roofing material 1, and a laterally extending triangular bent portion 10 formed at the lower end of the side wall of the cap 9 is recessed in the recess 2 of the roofing material 1. Fit into part 3. Thereby, the cap 9 and the roof material 1 are connected.

As described above, since the adjacent roofing materials 1 can be directly connected to each other without using a gutter or the like as in the related art, the roofing material 1 is installed in a distorted state due to an error in the installation dimensions of the gutters or the like. The roof material 1 can be easily constructed in a correct state without distortion.
In addition, the number of locking points between adjacent roofing materials 1 is reduced to one, so that even if the roofing material 1 is distorted due to an impact or external pressure, it is possible to reduce the number of locations where water is easily leaked and to improve the waterproof effect. Can be kept high. For this reason, the fixing strength of the roofing material 1 and the effect of preventing water leakage can be significantly increased. Further, it is possible to shorten the operation time of the sealing operation of the locking portion.

Locked to the roof surface with high locking force. For this reason, even if an impact or external pressure is applied to the upper surface of the cap 9 and a tensile force is applied to the side wall of the cap 9 upward, the cap 9 remains
It is locked to. Even if the pulling force is large, the triangular bent portion 10 of the cap 9 is squashed so as to spread laterally in the recessed portion 3 in which the cap 9 is fitted. I can maintain my strength.

In the gap between the roofing material 1 and the roof surface, an air layer holding block 14 is interposed. The air layer holding block 14 has a projection sheet 15 in which a plurality of projections 16 are arranged vertically and horizontally. A ventilation sheet 17 is laid on the upper surface of the airbag, and a waterproof sheet 18 is laid on the lower surface of the projection sheet 17. The air layer holding block 14 is flexible. Further, an air layer is formed inside the air layer holding block 14 by a plurality of air passages formed inside the air layer holding block 14, and the air in the air layer is heated to enhance the heat retaining effect. Further, by improving the flow of air in the air layer, the heat insulating effect is enhanced. Since the upper surface of the cap 9 is adjusted to the same level as the upper surface of the roof material 1, a roof having no irregularities is constructed.

Example 2 (see FIG. 7) In the figure, reference numeral 22 denotes a cap having an upper surface higher than the upper surface of the roofing material 1 and having a bent portion 23 projecting laterally at an upper end portion of the side wall. A bent portion formed at the upper end portion of the side wall of the roof member; 24, a solar collector serving as a member to be installed disposed on the upper surface of the roofing material 1; 25, a wooden cradle installed on the upper portion in the internal space of the cap 22; Is a nail for fixing the solar collector 24 to the cap 22, 27 is a storage space for piping wiring which is an internal space of the cap 22, 28 is piping, and 29 is wiring.

In a second embodiment shown in FIG. 7, a solar collector 24 is placed on the upper surface of the roofing material 1, and then the cap 22 is fitted into the recess 2 of the roofing material 1. Since the cap 22 in the second embodiment has an upper surface higher than the upper surface of the roofing material 1 and has a bent portion 23 formed at the upper end of the side wall of the cap 22, the bent portion 23 forms the outer peripheral upper surface of the solar collector 24. The solar collector 24 can be firmly fixed to the upper surface of the roofing material 1 without damaging the presser and the roofing material 1 with the nail 26 or the like. The solar collector 24 is fixed to the side wall of the cap 22 with nails 26. The pipe 28 and the wiring 29 connected to the solar collector 24 are stored in the storage space 27 of the cap 22 so that the appearance of the roof is not impaired.

Example 3 (see FIG. 8) In FIG. 8, reference numeral 30 denotes a glass wool material. Embodiment 3 shown in FIG. 8 is an example of a roof having a structure in which the cap 9 is not fitted in the recess 2 of the roof material 1. In this example, glass wool material 30 is filled between the roof material and the roof surface instead of the air layer holding block 14. The rainwater flowing into the concave portion 2 of the roofing material 1 is drained along the concave portion 2 and does not leak. Other codes, configurations and actions
The effect is the same as that of the first embodiment.

[0017]

According to the present invention, since the end portions of adjacent roof materials can be directly connected without intervening a gutter or the like as in the prior art, the roof material can be easily and promptly and reliably constructed, and the construction time can be reduced. Shortening and reduction of the burden on the operator can be achieved. Also, since it can be installed correctly without distorting the roof material,
Waterproofness and fixing strength were greatly improved. Furthermore, the number of locking points for connecting adjacent roofing materials is half that of the conventional one.
It was possible to reduce the number of locations, increase the water leakage effect, and maintain the waterproof effect for a long time.
